All sealant spray is a tar-free sealant based on rubber resin. After the coating has dried, the result is an adhesive, elastic protective coating that withstands even the highest athmospheric and mechanicals loads ( e.g. stone chipping). Sealant spray has a good sound insulation. The substrate should be dry, free of dust, grease and rust. Loose parts should be removed to avoid underrusting. Made in Germany, 400ml.
